Arranged to connect the front and rear axles is a reach 44, this reachbeing formed from a single length of tubing, one end of which-isslidingly fitted in the bore of aV sleeve 45, this sleeve beingsuspended from the rails 29 by means of a U'shaped strap hanger 46. Apair of hounds 47 are clamped by means of clevises or similar devices 48to the rear end portion of the sleeve and at their rear ends the houndsare fixedly secured in any preferred manner to the rear axle-tree 39..By this construction -eitherl of the rear supporting wheels 4may .dropinto a rut o'r advance over an obstruction 'Without distorting thereach, since the sleeve may rotate on the reach to-a slight extent.

i A pair of inclined brace rods 49 areconne'cted at. their rear ends.to' the rear bolster and attheirforward ends are bolted to the inclinedbrace rods 51 are loosely connected at their forward ends to the. frontIbolster 30, and at their rear ends are bolted to the reach as shown at52.

The means for permitting of the reach and rails of thektruck to swing inrounding a curve willnow be described. The middle portion' of the frontaxle 36 is preferably square as shotvn at 58 .and upony this squareportion of .the axle is mounted a ball 54, the same comprising a pair ofsimilar halves yprovided axially wlth angular openings 55 designed toreceive the squared portion of the axlejthese halves being securedtogether ,b means of lag screws 56 or similar means.

readed into the'peripbery of eachhalfy permitting of the axle swingingslightly when the vehicle is rounding 4a curve. It will 'be understoodthat during the swinging movement of the axle that the ball will swingwithinthe c oncaved surfaces of the halves. The halves are securedtogether by means of boltsor similar devices 61.

Although the axle has been described as ing formed in two pieces, itisnot intended to limit the construction to this particular form astheaxle may be made round and the ball may be cast in a single piecewithout departing from the spirit of the invention.

The corners of the body portion of the gear vhalves are rounded/as shownat 63, the object of whichI will presently appear.

Thereare two of the split rings, one arranged above the axle and the otherarranged below the axle, the

: intermediate portions of these rings slidingi ly fitting upon squareblocks 69 carried upon the axle, these blocks having axial openingsminals of 'each rin are bent outwardly as Shown. a-t70 and bo ted orotherwise secured as shown at 71 to thle leading end of the reach.

The terineaeoa these surfaces forming stops that prevent thereach from accidental engagement with the teeth of the sprocketgear whenmount ing. Bolts 75 are passed verticall` through the split rings andrigidly secure the saine together,7

Si housing; 76 is mounted on the bodyv portion of the sprocketgear, thishousing being made in two similar halves, each halt beingsubstantialljt7 seiiicircnlar in outline and being provided on its enteredge with an cut-tin'ned foot which is bolted or otherwise secured asshown at Ti to the outer face of the guide ring. Each halt is furtherprovided axially with circular opening 78 which registers with the outeredge of the adjacent it'rusto-conical opening; GO ci' the body portionof the gear 58 and permits of the axle, as above stated, swingingWit-hin the body portion of the gear.

lt is evident that should the reach he permitted to travel until thepins carried bj the ball engage the ends of the slots in the sprocketbody that these pins would in time beinjnred beyond repair and toprevent this, a pair of chain cables or the like as shown at Sl areenaifed at their forward ends upon the bearing` and are secured ,attheir rear ends to the' reach, these chains being snilicient length topermito'f the reach turning until the 'pins are nearly in engagementwith the ends ot the slots. These chains by t-lus Liiniting; theincrement ot the reach promote the longr lite ot the pins. An endlesslink chain@ is trained over the gear 58 and a gear 8O arranged upon therear axle By virtue of the ball and socket connection between the intenmediate axle and reach the chain will atall times be maintained thevertical plane of the reach. .Suspended by ineans of strap hangers 8lfrom the truck side rails is a reservoir S2 which may be illed Withgasolene or like fuel for supplying the engine *arricd by thefore-Wagon. t

lt will be seen from the above description thatl a vehicle has beenprovided which Will permit of the rearwheels dropping into ruts oradvancing over obstructions`v Without straining the reech and furtherthat by the novel bali andsocltet connection between the toi-Ward end ofthe reach and the intermediate "wheel axle that the reach and rearportion ot the truck may`I swing' in rounding' a cui-*ve Withoutdistorting the axle in anyv manner. Further, it will be olisei'ifcdthatby uieans of the chains Sl, the i from traveling in the oi more .'ientat the s promoted and it inr- 'ed that by forming` the sprocket Wheel.and balls as above described, the pins may be readiliT removed Whenwornand replaced With new ones.

ln order that the traction wheels othe .vehicle an en adjust' themselveswhen the truck truck may lis swinging around a curve, a ratchet Wheel 83isl arranged Within the liiib ol each traction Wheel and is keyed to theaxle. A 1nlurality et rollers Se surrounds the ratchet Wheel, theserollers binding; against the teeth or" the Wheel and confronting innerWall of the huh during-f rotation or the axle. Now it is evident: thatin swinging; around a turn the traction wheels on one side oi' the truckwill more the same rate as the axle, While the traction Wheels on theopnosite side ci the trnclt iniist more ta 'faster rete than the axle.

When trie wheels rotate faster than the axle the rollers 'will drop intothe Valleys 'of the teeth and out ot trictional engagement with theWheel so thaty the Wheel may rotate independently and faster than theaxle. AL though this specie-orm ot' ratchet is shown it is evident thatmodications may be iliade in the construction of the ratchet Withoutsacrificing any of the adi'antagesoi the invention. l
